Question

Explain virtualization and hypervisor in cloud computing

Answer 1

Virtualization improves IT resource utilization by treating your company's physical resources as pools from which virtual resources can be dynamically allocated.

Virtualization involves a shift in thinking from physical to logical, treating IT resources as logical resources rather than separate physical resources. Using virtualization in your environment, you are able to consolidate resources such as processors, storage, and networks into a virtual environment which provides the following benefits:

Consolidation to reduce hardware cost.Optimization of workloads.IT flexibility and responsiveness.

Virtualization is the creation of flexible substitutes for actual resources — substitutes that have the same functions and external interfaces as their actual counterparts but that differ in attributes such as size, performance, and cost. These substitutes are called virtual resources; their users are typically unaware of the substitution.
